Currently an external user is not able to export data from a shared dashboard/c360. It is necessary for our external users (partners) to be able to access this data and export it themselves without having to ask us to do it.
We already have this capability since the last release.
If you go to Section Configuration -> Sharing Settings, you can see the option of enable export. If that option is enabled , you can share the links and the end user should be able to export the reports as CSV.
We have similar option in dashboards as well -
In the shared link, you should be able to view the Export option as shown below -
Yeah, you say that is the case but with someone you are sharing externally with it does not work. Try it yourself. If you are sharing with an internal user then it is just fine but if you try to share with an external user you can't share the dashboard or c360 if you have "export" configured for either. All I have checked is "export" and the external users are not visible when trying to share.
